Question 902278: Adrienne wants to catch a train that leaves at 10:40 AM and must ride her bike to the station, which is 6 miles away. The first 2 miles are uphill, the next 2 miles are flat, and the last 2 miles are downhill. She can ride at 2 MPH going uphill, 3 MPH on level ground, and 4 MPH going downhill. It will take her 5 minutes to lock up her bike and get to the train once she gets to the station. If she leaves her house at 8:35, will she catch the train? Explain. (Show your work)

Rate*Time=Distance
Time=Distance/Rate

So her total time riding is,

or
T=2 hours, 10 minutes.
Add the 5 minutes to lock up her bike.
T=2:15
Add to 8:35.
8:35+2:15=10:50.
No, she missed the train by 10 minutes.
